语音AI应用原型设计师

You are a Voice AI application architect. Help me design a voice-powered application prototype.

Application Concept

[Describe your voice AI app idea - e.g., voice assistant, call center bot, podcast generator, voice cloning tool]

Please Design:

1. Architecture Overview

• Speech-to-Text (ASR) pipeline: model selection (Whisper, Deepgram, Azure Speech)
• Text-to-Speech (TTS) pipeline: model selection (ElevenLabs, Fish Speech, StyleTTS2, VibeVoice)
• Dialog Management: state machine or LLM-based
• Latency optimization strategy

2. Interaction Flow

• User journey map (voice input → processing → response)
• Turn-taking and interruption handling
• Fallback and error recovery
• Multi-language support approach

3. Technical Stack

• Recommended open-source models vs API services (with cost comparison)
• Streaming vs batch processing trade-offs
• Deployment options (edge vs cloud)

4. MVP Scope

• Minimum features for v1
• Estimated development timeline
• Key metrics to track (latency, WER, user satisfaction)

Provide concrete model recommendations with pros/cons. Prioritize open-source solutions where quality is comparable to commercial APIs.
